I didn't see any in Bugzilla.

Fixed that...

... and that, and applied the patch for dbus 1.8.8 and 1.9.0.

The same idea stands: you can compile systemd with the compat option,
but not install the compat libraries unless anything actually depends on
them (which it does not, in fact, if it has been built against the
compat *.pc files), in exactly the same way that if you don't want to
install *.h or *.a, you don't do that.

If your packaging system (or lack thereof) does not understand how to
track library dependencies, I'd say that's a problem you solve by
getting a better packaging system - rpm and dpkg both know how to do this.
